SCRUBBING .AND MOPPING- MACHINE.

Macnee.

V To all w/mma't may concern Be it known that I, ENRICO GALLO, a citiyzen of the United States of America, residing at Pittston, in the countyof Luzerne and State of Pennsylvania', have invented certain new anduseful- Improvements iii Scrubbing and Mopping Machines, of which thefollowing is a specification, reference being had .therein to theaccompanying drawing.

This invention relates to Hoor scrubbing machines and has for itsprincipal object the production of a simplev and efficient device* whichwill eliciently scrub the floor as the brushes are being soape'd. A

Another object 'of this invention is the production of a floor scrubbingmachine wherein a plurality of housings are employed for the carrying ofsoap bars in such anianner as to be readily engaged by the horizontallyrotating brushes so that as the brushes are supplied with waterthey willbe soaped for cleansing the floor. 1 With these and other objects inviewthis invention consists of certain novelcombinations, constructions, andarrangements of parts as will be hereinafterl fully described andclaimed.

In the'accompanying drawing: Figure 1 vis a central longitudinal sectionof the scrubbing machine, as constructed inaccordnce with thisinvention; Fig. 2 -is .in enlarged y longitudinal section of the forwardportion of the scrubbing machine showing the manner in which the soap isfedto the brushes. Fig. 3 is a section taken on the line-3--3 of FiaQ--By referring'to the drawing it will be seen that l designates the outercasing which is supported upon a lurality of forward wheels 2 and aplurality of rearward wheels 3. Thecasing 1 carries near the frontthereof a pair of brushes 4, which brushes aresupported 'upon thecasing 1. under the platform 5. The platform 5 carries al plurality lofsoap containing housings 6 in which are placed soap bars or cakes 7. Apressure late 8 is carried upon each soap bar or block 7 and each plate8carries a spring 9 for urging a downward pressure upon the soapbars 7and thereby normally holding the soap bars in firm engagement with thebrushes 4.

As clearlyv illustrated in these brushes are employed, each brushcooperating' with a soap bar for facilitating' Specification uf Letters.Patent.

the y Soaping of the brush to assist in scrubbing the floor over whichthe machine is adapted to travel.

One of the brushes v4 is driven by means of a sprocket chain 10, while asprocket chain 11 is placed upon the opposite side of the casing 1, asshown in Fig. 3, and these chains lO'and 11n/are adapted tobe driven byany 'suitable sprocket,vnot deemed necessary `to be herein disclosed,carried by the forward wheels 2, which` are mounted upon the aXle14. n

A watergupply tank 15 is supported within the main casing 1, and thiswater supply tank 15 tapers toward the bottom and top thereof toconstitutea substantially diamond The tank partition 16 through whichextends the valve 17 for normally closing the aperture 18 formed in thepartition 16. The valve 17 is carried by a vertically extending plunger19 upon which plunger is carried^ a coil spring 20 for normally urgingadownward pressure upon the valve 17. The upper end of the spring 20engages the inner end of the tank 15 as clearly illustrated in Fig. 1.It should be understood .that a suitable door 21 inaybe employed for the4purpose offilling the tank 15. Asclearly illustrated in Fig. 1, thepartition- 16 is spaced from the lower end of the tank 15.

A waterl discharge pipe-22 communicates with the tankrl below thepartition 16, and this water discharge pipe is provided with aplurality' of apertures 23 near the lower end thereof. The pipe 22 isalso providedwith laterally extending sections24 which are alsoperforated as indicatedat 25 for evenly dfstributing water throughoutthe entire length of the brushes 4. The water, of course, will bedischarged upon the floor which'is being scrubbed, and by rotating thebrushes 4 it will be seen -that a floor may be scrubbed easily andreadily cleaned by moving the casing 1 back and forth according to thedesire ofthe operator.

.From the foregoing description it will be seen that a very simpleand-efficient floor 'scrubbing machine has been provided,.`

wherein the soap housings will efficiently carry 'the soap bars by meansof the lower -`portions, as clearly" shown in Fig. 2, while Y Havingthus ndescribed the invention 1s claimed as new, isz- I,is sprayedby unebrushes and the brushes rotated, they will engage the soap and bycontinuous action will scrub the floor.
